Once your immune B and T cells are done repelling invaders to your body, these cells are no longer needed, so they start to clump, pop a hole in their own nuclei, shrivel like a raisin, and die. Win or lose, these cells will die. It's cell suicide—a programmed cell death called apoptosis.
Why does this happen? The individual cells die to allow the body to conserve enough energy to be able to fight the next fight. It's really an example of how our cells have the machinery to commit suicide before they sap too much of your energy on a long-term basis.
Most cells turn off their apoptosis genes for the sake of the survival of the species. But immune cells are different. Your body uses these bit players to fight the infection, then kills them off so that your brain and heart and liver and all of your other organs can be supplied with the energy needed to take center stage.
Apoptosis is also how injured or imperfect cells are removed. When our quality control isn't working at its best, this can cause aging either because we do not make our cells quite perfect enough or because we are too strict. This is great when we're young, but it can age us as we get older.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
